Question

how do u 7c3d2/21c2d3

Answer 1

=c/3d

Answer 2

Okay lets break this apart:

First take the first term which is 7/21 = 1/3

Then next: c^3/c^2 = c3-c2 = c^1

Then Last: d^2/d^3 = d2-d3 = d^-1 which means that we have to put d^-1 in the denominator as it is negative

Gving our final answer to be 1c/3d

Answer 3

7c^3d^2/21c^2d^3
Let's take this term by term.
7 * c^3 * d^2 / 21 * c^2 * d^3
The 7/21 becomes 1/3

The c^3/c^2 is the law of exponents, so you have: c^3-2 = c^1 = c
The d^2/d^3 is the law of exponents, so you have: d^2-3 = d^-1 = 1/d
So your final answer is:

1/3 * c * 1/d which can be rewritten as:
c/3d
